Have been thinking for some time to put a gun for sale here on thefiringline.com but don't know the proper steps. Can someone point me in the right direction as far as how you get paid, where you ship the gun, etc.
List the thread in the For Sale or Trade forums with your state in the title.
Payment arrangements are on you. Cash or Paypal gift or money order are most popular. Face-to-face for an in-state sale, or transfer through an FFL for out-of-state.
